Control alert messages about lost interrupts.
Supported values: ON, OFF
Default: ON
A lost interrupt occurs when a driver or board requests a service
with an interrupt call and then drops the request before the
processor can respond.
Lost interrupts generate the following message: Interrupt
controller detected a lost hardware interrupt.
This message indicates a hardware or driver problem that could
degrade performance.
Unload all drivers and then reload them one at a time to
determine which driver has a problem. Then contact the vender
of the driver.
Set the parameter to OFF while you are waiting for a resolution.
You can set this parameter in the STARTUP.NCF file.
Control alert messages about spurious interrupts.
Supported values: ON, OFF
Default: ON
A spurious interrupt occurs when hardware in the server creates
an interrupt that is defined and reserved for another device.
Spurious interrupts generate the following message: Spurious
hardware interrupt <number> detected.
This message indicates a serious error in the hardware.
If your server console displays this message, remove all add-on
boards and run SERVER.
If the message doesn't appear, add the boards one at a time to
determine which hardware is creating the spurious interrupt.
Then contact the vendor.
Set the parameter to OFF while you are waiting for a resolution.
You can set this parameter in the STARTUP.NCF file.
